URL encoding and decoding, explained and instant
This URL encoder/decoder converts text to and from percent-encoding instantly. Component mode encodes every reserved character - what you want for a single query-string value - while full-URL mode leaves structural characters like/, ?, and & intact so a whole address stays valid. Decoding also treats + as a space, matching how forms submit data.
Paste a full URL and the tool additionally breaks its query string into a table of decoded key/value pairs, which is the fastest way to read a long tracking or OAuth redirect URL. Everything runs in your browser with the standard encodeURIComponent APIs - no uploads, no logging, works offline.
